Hi forumites,
several reasons for me
1) improvising and problem solving training helps you all the time, even in your "normal" environment
2)when on field exercises with my reserve unit, i need a lot of those "survival" or "field-craft" skills
3)I can think of a lot of scenarios where you would need it, even in the middle of overcrowded Europe, for instance: you go skiing, its getting late and dark, maybe fog or heavy snow, where it may be better to not descend any more, or you risk breaking your neck. with my kit it would be no problemo to stay on the mountain ver night
4) IT´S FUN
